Type Checking

Check for what you need

Mainly for framework developers, although it is just as usable in an app

Installation

npm install --save type-checking

Usage

• By registering (recommended, but can cause conflicts)

 
  require('type-checking/register')('responds_to')
 
  array = []
 
  array.responds_to 'indexOf' #true 
  array.responds_to ['indexOf','join','concat'] #true 
 
  class ArrayInterface
    indexOf:->
    join:->
    concat:->
 
  array.responds_to ArrayInterface #true 
 

• Directly

 
  responds_to = require 'type-checking'
 
  array = []
 
  responds_to array, 'indexOf' #true
